Quality Control

Our production of this advanced polymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as NCO/OH equivalent weight, viscosity, solids content, and thiol content are rigorously monitored using advanced analytical techniques. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed, moisture-proof container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures recommended for the specific grade, typically between 15°C and 25°C. Keep away from heat, sparks, and open flame. Due to the reactive nature of the components, isolate from strong oxidizing agents, acids, bases, and moisture to prevent premature polymerization or degradation.
